CUTLER-Y CLEAN Application filed August 31, 1925. Serial No. 53,4;2'7.

The main object of this invention is to provide a device for grinding, sharpening, and cleaning cutlery. The device essentially consists of a plurality of rouge disks and a grinding wheel which are mounted on a shaft and are rotated either manually or thru another source of power, and when brought into contact with an article of cutlery such as a knife or fork, are adapted to clean and polish the same.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a front elevational view of the cleaner and polishing machine.

Figure 2 is a top plan view of the same.

Figure 3 is an end elevational view of Figure 1.

Figure 1 is a longitudinal partially sectioned elevational view of a portion of the shaft, showing the means provided for shifting the position of one of the rouge wheels to compensate for various thicknesses of knife blades.

Referring in detail to the drawing, the numeral 10 indicates the base upon which the entire device is mounted. At both the ends of the base, a pair of standards 11 and 12 rise upwardly and have annular horizontal openings at their upper ends in which are journalled the ends of a spindle 13 which has a crank handle 14; fixed to one end thereof. These shafts are retained in place by caps 15. A flat surface is provided on the top of these caps for the purpose of forming a seat for the ends 16 of semi-oval straps 17 and 18 which form yokes above and below the spindle 13. The lower strap 18 is not connected to the flat surfaces of the caps but is connected instead to the sides of the standards 11 and 12. Mounted intermediate the length of the spindle are a pair of rouge disks 19 and 20. The rouge disk 19 is rigidly mounted in place on the spindle. The disk 20 is adapted to slide longitudinally on the spindle 13 by mounting the layersof fabric 21, of which the rouge disk is composed. on a collar 22 which is flanged at both ends and at one of the flanged ends is provided with a key 23 rigid with the collar which is adapted to be guided and slid in a longitudinal channel 2a extending lengthwise on the spindle 13. This key forms part of the substantial flange 25 integral with one end of the sleeve and is adapted for the purpose of permittingthe rouge disk 20 to be moved longitudinallyof the spindle 13 and at the same time rotate with the latter. Positioned at a point distant from the collar flange 25, an additional flange 26 is rigidly mounted on the spindle for the purpose of retaining the coiled spring 27 in place on the spindle between said flange 26 and the collar flange 25, which is provided for the purpose of urging the rouge disk 20 toward the fixed rouge disk 19. so that the adjacent faces of both disks may contact with each other. The mutually adjacent surfaces of the disks 19 and 20 have convex surfaces so that a knife or the like may be readily inserted between both disks when it is desired to clean and polish. the same. On the straps 17 and 18 above and below the disks where their convex surfaces contact, are spaced-apart lugs 27 between which a knife is adapted to be guided. in a vertical plane when cleaning said knife between the rouge disks 19 and 20. Near one end of the spindle adjacent the rouge disk 19 are a plurallty of relatively small oval-edged rouge rollers 28 which are mounted on the spindle, one alongside the other, and are separated by a small gap 29 in which a fork or other cutlery utensil which may not be cleaned and polished between the rouge disks 19 and 20, is inserted. At the end of the spindle opposite to the crank handle 14 is a earborundum wheel 30 rigidly mounted on said spindle and is used for the purpose of providing knives or other cut-ting utensils with cutting edges in the well known manner. Mounted on the bottom side of the strap 18 is a housing 31 in which a drawer 32 is slidable. said drawer being used for the purpose of storing the rouge compound with which the surfaces of the disks 19 and 20 and rollers28 are treated.

In using this device for cleaning cutlery such as a knife, fork, or the like, the spindle 13 is rotated. If the article to be cleaned is a knife, the same is placed upon the vertical edges of the straps 17 and 18 and guided in a vertical plane between the rouge rollers 19 and 20. The spindle in being rotated causes the convex surfaces of the mutually adjacent sides of therouge rollers to clean and polish the article. When forks are to be cleaned, the same are inserted in the gaps 29 between the rollers 28 and the spindle is likewise rotated. Spoons and thelike are key which registers in a slot in the spindle,

thus locking the collar rigidly to the spindle and at the same time'permitting longitudinal movement of the disk 20, it being normally urged in contact withthe' disk 19 by the spring 27. i 3 Iclaimz In a cutlery cleaner, a rotating spindle,a

, flange on one side of the center of said spindie, a diskfixed tosaid spindle havinga convex surface, a movable disk mounted slidably adjacentthe fixed disk, saidmovable disk having a complemental convex suryface, the convex surfaces'of the fixed and movable forming a substantially triangular-channel between said disks, a sleeve forming part of the movable disk and slidably mounted on said spindle, said spindle having aslot extending diametrically thru the spindle, a key rigid with the sleeve registering in the slot'in said spindle, a spring surrounding said spindle between the flange and the sleeve of the movable disk urging said movable disk against said fixed disk, spaced-apart standards supporting said spindle at its ends, a pair of oppositely curved straps having their ends attached to said standards, and spaced-apart lugs projecting fromsaid straps intermediate their "length, said lugs being positioned above and below the fixed and movable disks, the chan nel between said lugs beingaligned with the triangular space between said fixed and movable disks, said lugs forming a guide for cutlery. a

In testimony whereof I afiix my signature.
